path¶: A String specifying the path to an existing output database (.odb) file.
readOnly=0¶: A Boolean specifying whether the file will permit only read access or both read and write access. The initial value is False, indicating that both read and write access will be permitted.
readInternalSets=0¶: A Boolean specifying whether the file will permit access to sets specified as Internal on the database. The initial value is False, indicating that internal sets will not be read.

Returns:¶

An Odb object.

Return type:¶

Odb

Raises:¶

OdbError – If the output database was generated by a previous release of Abaqus and needs upgrading. Run abaqus upgrade -job <newFilename> -odb <oldFileName> to upgrade it.
OdbError –
opened. – If the output database was generated by a newer release of Abaqus, and the installation of Abaqus needs upgrading.

upgradeOdb(existingOdbPath, upgradedOdbPath)[source]¶

This method upgrades an existing Odb object to the current release and writes the upgraded version of the Odb object to a file. In addition, Abaqus/CAE writes information about the status of the upgrade to a log (.log) file. You can access this method using either of the following techniques:

From a script running outside Abaqus/CAE. For example:

import odbAccess
odbAccess.upgradeOdb(existingOdbPath='oldOdb', upgradedOdbPath='upgradedOdb')

From the session object in Abaqus/CAE. For example:

import visualization
session.upgradeOdb(existingOdbPath='oldOdb', upgradedOdbPath='upgradedOdb')

Note

Check OdbCommands.upgradeOdb on help.3ds.com/2020.

Parameters:¶

existingOdbPath¶: An String specifying the path to the file containing the output database to be upgraded.
upgradedOdbPath¶: An String specifying the path to the file that will contain the upgraded output database.

Raises:¶

OdbError – If the output database upgrade fails.

description : --is-rst--:py:class:`str` = ''[source]¶: A String specifying the contents of the frame. The default value is an empty string.

domain : --is-rst--:py:class:`~abaqus.UtilityAndView.SymbolicConstant.SymbolicConstant`[source]¶: A SymbolicConstant specifying the domain of the step of which the frame is a member. Possible values are TIME, FREQUENCY, and MODAL.

fieldOutputs : --is-rst--:py:class:`dict`\ \[:py:class:`str`, :py:class:`~abaqus.Odb.FieldOutput.FieldOutput`] = {}[source]¶: A repository of FieldOutput objects specifying the key to the fieldOutputs repository is a String representing an output variable.

frameValue : --is-rst--:py:class:`float`[source]¶: A Float specifying the value in units determined by the domain member of the Step object. The equivalent in the time domain is stepTime; in the frequency domain the equivalent is frequency; and in the modal domain the equivalent is mode.

frequency : --is-rst--:py:class:`float` = 0[source]¶: A Float specifying the frequency. This member is valid only if domain = FREQUENCY or if the procedureType member of the Step object=FREQUENCY. The default value is 0.0.

incrementNumber : --is-rst--:py:class:`int`[source]¶: An Int specifying the frame increment number within the step. The base frame has normally increment number 0, and the results run from 1. In case of multiple load cases, the same increment number is duplicated for each loadcase.
